Theodor Friedrich Ludwig Nees Von Esenbeck
Theodor Friedrich Ludwig Nees von Esenbeck (26 July 1787 – 12 December 1837) was a German botanist and pharmacologist, who was born in Schloss Reichenberg near Reichelsheim (Odenwald). He was a younger brother to naturalist Christian Gottfried Daniel Nees von Esenbeck (1776–1858). Career In 1805 Nees von Esenbeck was an apprentice to pharmacist Wilhelm Martius in Erlangen, and in 1811 moved to Basel, where he worked for the Bernoulli family at the ''Goldenen Apotheke''. In 1817 his friend, zoologist Heinrich Kuhl (1797–1821) procured an assignment for him at the University of Leiden as a reader of botany, and shortly afterwards, with the help of botanist Sebald Justinus Brugmans (1763–1819), he held a position at the botanical gardens in Leiden. In 1818 he earned his doctorate at the university, and subsequently moved to Bonn, where he worked at the botanical gardens. In 1827 he attained the title of "full professor" at the University of Bonn, where he was a colleague o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bonn
The federal city of Bonn ( lat, Bonna) is a city on the banks of the Rhine in the German state of North Rhine-Westphalia, with a population of over 300,000. About south-southeast of Cologne, Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants. It is a university city and the birthplace of Ludwig van Beethoven. Founded in the 1st century BC as a Roman settlement in the province Germania Inferior, Bonn is one of Germany's oldest cities. It was the capital city of the Electorate of Cologne from 1597 to 1794, and residence of the Archbishops and Prince-electors of Cologne. From 1949 to 1990, Bonn was the capital of West Germany, and Germany's present constitution, the Basic Law, was declared in the city in 1949. The era when Bonn served as the capital of West Germany is referred to by historians as the Bonn Republic. From 1990 to 1999, Bonn served as the seat of government – but no longer capital – ...

Pharmaceutical
A medication (also called medicament, medicine, pharmaceutical drug, medicinal drug or simply drug) is a drug used to diagnose, cure, treat, or prevent disease. Drug therapy (pharmacotherapy) is an important part of the medical field and relies on the science of pharmacology for continual advancement and on pharmacy for appropriate management. Drugs are classified in multiple ways. One of the key divisions is by level of control, which distinguishes prescription drugs (those that a pharmacist dispenses only on the order of a physician, physician assistant, or qualified nurse) from over-the-counter drugs (those that consumers can order for themselves). Another key distinction is between traditional small molecule drugs, usually derived from chemical synthesis, and biopharmaceuticals, which include recombinant proteins, vaccines, blood products used therapeutically (such as IVIG), gene therapy, monoclonal antibodies and cell therapy (for instance, stem cell therapies) ...

Lithography
Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and actor Alois Senefelder and was initially used mostly for musical scores and maps.Meggs, Philip B. A History of Graphic Design. (1998) John Wiley & Sons, Inc. p 146 Carter, Rob, Ben Day, Philip Meggs. Typographic Design: Form and Communication, Third Edition. (2002) John Wiley & Sons, Inc. p 11 Lithography can be used to print text or images onto paper or other suitable material. A lithograph is something printed by lithography, but this term is only used for fine art prints and some other, mostly older, types of printed matter, not for those made by modern commercial lithography. Originally, the image to be printed was drawn with a greasy substance, such as oil, fat, or wax onto the surface of a smooth and flat limestone plat ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Düsseldorf
Düsseldorf ( , , ; often in English sources; Low Franconian and Ripuarian: ''Düsseldörp'' ; archaic nl, Dusseldorp ) is the capital city of North Rhine-Westphalia, the most populous state of Germany. It is the second-largest city in the state and the seventh-largest city in Germany, with a population of 617,280. Düsseldorf is located at the confluence of two rivers: the Rhine and the Düssel, a small tributary. The ''-dorf'' suffix means "village" in German (English cognate: ''thorp''); its use is unusual for a settlement as large as Düsseldorf. Most of the city lies on the right bank of the Rhine. Düsseldorf lies in the centre of both the Rhine-Ruhr and the Rhineland Metropolitan Region. It neighbours the Cologne Bonn Region to the south and the Ruhr to the north. It is the largest city in the German Low Franconian dialect area (closely related to Dutch). Mercer's 2012 Quality of Living survey ranked Düsseldorf the sixth most livable city in the world.

Carl Ludwig Blume
Charles Ludwig de Blume or Karl Ludwig von Blume (9 June 1796, Braunschweig – 3 February 1862, Leiden) was a German-Dutch botanist. He was born at Braunschweig in Germany, but studied at Leiden University and spent his professional life working in the Dutch East Indies and in the Netherlands, where he was Director of the Rijksherbarium (state herbarium) at Leiden. His name is sometimes given in the Dutch language form Karel Lodewijk Blume, but the original German spelling is the one most widely used in botanical texts: even then there is confusion, as he is sometimes referred to as K.L. Blume (from Karl). He carried out extensive studies of the flora of southern Asia, particularly in Java, then a colony of the Netherlands. From 1823 to 1826 Blume was Deputy Director of Agriculture at the botanic garden in Bogor (Buitenzorg) in Java. In 1827 he became correspondent of the Royal Institute of the Netherlands. In 1855, he was elected a foreign member of the Royal Swedish Ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombacoideae
Bombacoideae is a subfamily of the mallow family, Malvaceae. It contains herbaceous and woody plants. Their leaves are alternate, commonly palmately lobed, with small and caducous stipules. The flowers are hermaphroditic and actinomorphic; the calyx has 5 sepals united at the base, which are not accompanied by an epicalyx (involucel). The corolla has 5 free petals and an androecium of numerous stamens, typically with free filaments which are not fused in a staminal tube (column). The pollen is smooth and the ovary superior and pluricarpellate. The fruits are schizocarpous or capsular. Genera Classification Some taxa in this subfamily were previously grouped under the now-obsolete family Bombacaceae, as recent phylogenetic research has shown that Bombacaceae as traditionally circumscribed (including tribe Durioneae) is not a monophyletic group. ''Camptostemon'', ''Lagunaria'', '' Pentaplaris'' and '' Uladendron'' might more appropriately be placed in Malvoideae, as might the tri ...

Ludwig Clamor Marquart
Ludwig Clamor Marquart (29 March 1804 – 10 May 1881) was a German pharmacist and entrepreneur born in Osnabrück. As a teenager, he was a pharmacist’s apprentice in the town of Dissen, and afterwards an assistant pharmacist in Lingen and Werden. Later he was an overseer of pharmacies in the district of Cologne, and in 1835 received a doctorate in pharmaceutical chemistry from the University of Heidelberg. In 1837 he started a private pharmaceutical institute in Bonn, where he taught classes until 1845. One of his students at the institute was renowned chemist Remigius Fresenius (1818-1897). In 1845 he founded in Bonn, ''Marquart's Lager chemischer Utensilien'', a factory that produced fine chemicals and pharmaceuticals. Today the operation in Bonn is part of Evonik; thus making it one of the oldest producers of chemicals in Germany. In 1835 Marquart is credited for coining the chemical term "anthocyanin" to denote the blue pigment of the cornflower. In 1842, Justus Carl Hass ...

Taxonomy (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolu ...
